Each security camera is different, so predicting “how long footage will be stored” is problematic. However, it is directly proportional to your need for the footage when deciding to store it.

If you plan to keep footage for no more than a month, you can purchase a cheaper security camera. But to store valuable evidence for a longer time, you should use a surveillance camera system with a high-definition video. So that you can store footage for a longer time.

Most cameras and smaller external recording devices store their footage for up to 30-90 days. Also, many camera brands offer cloud storage packages that allow you to store footage for longer periods of time.

How Long Do Street Cameras Keep Footage?

In general, most security camera footage is kept for 30 to 90 days (1 to 3 months at the most). In some cases, footage of the constant street camera stream of intersections is available for 30 days.

If they’re using digital recorders, the length of storage capacity can range from 7 days to 4 or 6 months depending on the size of the hard drive.

Transportation Departments may require more than this, but they will not retain red-light camera footage for South Florida car accidents longer than 30 days.

What Happens to the Old Security Cameras?

Security camera networks generally have a limit to how long they can store video footage. As security footage is saved to SD cards, cloud storage, or hard drives, the old footage is overwritten by the new.

Furthermore, if your storage space is sufficient to store two weeks of surveillance footage, it will be possible to retrieve two weeks at any given time.

When dealing with an entire hard drive, you can adjust this setting via your NVR’s web interface and let it overwrite older footage.

Besides, when using an older model, you can delete footage manually, which can be difficult if the NVR doesn’t display how much space is left on its hard drive.

How Long Do Security Cameras Keep Footage?

Generally, it depends on many factors, one of the most important two factors are:

Average industry size

Nowadays, most security cameras record their footage digitally, allowing them to be stored for longer. Schools, retail stores, supermarkets, and hotels are some institutions storing video footage differently with time variation.

Schools, retail stores, supermarkets, hospitals, and hotels keep videos for between 30 and 90 days. As a result, footage can be kept for as little as 7 days or as long as several years, depending on the security needs.

Additionally, they are migrating to digital storage as technology advances, allowing them to keep footage for a longer period.

As per Law

No laws restrict surveillance camera storage in the United States, so surveillance security cameras may retain video footage as long as necessary. Keep in mind; it is only legal to record people legally in those places unless the person reasonably expects privacy.

How is Video Footage Stored?

First, consider how security cameras store video recordings. Depending on your needs, preferences, and resources, you can store video files in several ways.

Modern systems have replaced outdated technologies such as VHS tapes and DVDs for storing the videos of security cameras on a disk. However, there are several options available nowadays, including:

  • Hard disk drives
  • SD cards
  • A cloud storage service.

Cloud-based space:

Nowadays the most common practice is to store camera footage on cloud servers. Many workplaces use this way, allowing a large number of users to access it without compromising security. It allows you to store data or footage for a longer time than other storage methods.

Comparison of NVRs and DVRs:

NVRs consists of a network of IP cameras connected by a digital network. This method allows you to access IP footage through your smartphone’s app or browser.

Whereas, digital video recorders (DVRs) use analog security cameras attached by coaxial cable. With cloud technology, more security camera systems offer remote access and convenience, and NVRs can now be found in more security camera systems. Read more about NVR and DVR

SD Card Storage

You can use SD cards as external storage devices to capture and store footage. This is a reasonable option if you want to keep much footage for longer.

Also, it is a popular storage option for camera footage. You can buy one with lots of storage capacity and is inexpensive.

How Much Storage Does a Security Camera Have?

Security camera storage amount depends on several things, such as the storage method, the number of cameras, and the applications. If your security system records footage onto your hard drive, you typically have one week or month of video storage.

You cannot view video files unless uploading them onto an external device, such as a thumb drive or computer. Even though most cameras have built-in memory, so most businesses store security footage on external devices.

Therefore, when purchasing a security camera, you should consider how much storage it offers and what types of storage methods and devices it is compatible with.

What Happens to Old Security Footage?

Your security camera’s hard drive will overwrite older footage with new footage once it reaches its maximum capacity. Since the old video is automatically deleted. That’s why you will always have the most recent video.

You can store video footage within your system’s capacity, but once the old footage has been deleted, you cannot access it again. Alternatively, you can delete the footage manually by adjusting your device’s settings.

Bottom Line

Security cameras are a great way to keep an eye on your property or business, but how long do they typically store footage? The answer is that security cameras can store footage for anywhere from 30 days to 90 days.

It depends on the camera model and storage capacity, so you should know what you’re getting before making a purchase.
